LEONE, citis. residing in Cleve-- not of tlnvahogs and State ii'Hi certain new and useinvention relates to pne- "rs or cleaners, en'ipl jvin a tan s un exhaust to than: n 'ust the invention is to provide wrizcd by nov the. arrangenozzle and m" means for drivcity 1 men; 111i tan. and ing the fan.

The fan casing 1' il/ontally arranged, that on a min-:11 :ehnl'i, adjacent to the suction nozzle, anal t is driven from the main or wheel she means of spiral the parts heing so arranged that who machine occupies a comparatively small spit and hence may he used in confined o nf ons.

of Fig. 1. :ally to the drawings,

ulicates a handle w ieh is connected h of; to the main shett N which turns the yoke. This wheels I, loose achine is pushed h a pin one wheel and the n back motion.

es lo 1 Ellill re pinion 5O 1 casing a 5:3. fast o Th the casings D '1 is gear H is d e line of the "ral gear 86 in an exten hag sutiicien'tly porous to pass the air but sion F of the casing F, and rotating on hall bearings T therein.

The lower end of the vertical using F is fastened to the top of the. fan casing 91, within which is a horizontal fan 81 fastened to the lower end of the shaft 85. The fan casing is secured to the exhaust nozzle 92, which opens into the fan casing through the eye 99 at the center of the fan and the *asing has at one side an outlet 93, to a hagor other receptacle 16 placed to receive the dust. The mouth of the nozzle 92 is elongated transversely of the machine and is open on the underside to pass close to the floor, being supported in proper relation thereto by means of rollers 90 at opposite ends of the nozzle.

As shown in Figs. 3 and 4 the shaft N is mounted in hearings 75 attached on top of the tan casing 91 and passes across between the gear casing F and the fan casing 91, wh ch gives a very compact arrangement, and enables most of the Weight or" the machine to be carried by wheels A, insuring sullicient traction to operate the fan The space occupied-by the machine is small and thus it may he got into corners, and conveniently operated in small rooms, and also easily transported from one room to another, or up and down stairs, the machine heinglsufiiciently balanced to enable it to be lifted by the handle P.

In operation, when the machine is pushed over a floor the Wheels A drive the gear C through the clutch and sha and this gear drives the countershaft M, piral gear H, spiral gear. Sound fan shaft 85, thereby rotating the fan which causes a suction through the nozzle delivering the dirt and dust to a suitable collector, which may be a catch the dust. 1 v

The nozzle is supported with its mouth adjacent-to the floor by means of the rollers 90 thereunder. and hence the mouth of the nozzle will follow any irregularities or inequalities in the floor irrespective of the nu: wheels A, whereby the nozzle will follow inequalities such as the edges of rugs or carpets door treads or the like and the nozzle will he held at all times in close position to the place of suction on the floor. The rear roller Wacts to prevent excessive swing of the nozzle and fan casing.

Having thus described my invention,what

'1 claim as new and desire to secureby Letters Patent is I 1. In a carpet sweeper, the combination of driving wheels, a horizontal shaft supported thereby, a horizontal fan casing mounted between the wheels and under said shaft and driving wheels, a horizontal shaft supported thereby, a horizontal fan casing located between the wheels and suspended in swinging relation from the shaft and under the same, a rotary fan in the casing, having a vertical shaft extending 'through the top thereof, a gear casing fixed on top ofthe fan casing, gearing in said casing between the first mentioned shaft and the fan shaft, and a suction nozzle secured to the underside of the fan casing and communicating therewith. I

3. In a carpet sweeper, the combination of a Wheeled driving shaft, a horizontal fan casing having bearings through which the said shaft extenc s, said casing being located under the shaft and arranged to swing on said bearings, a fan in the casing having a vertical shaft projecting upwardly beside the driving shaft, a gear casing fixed to the top of the fan casing a horizontal countershaft extending into said gear casing, gearing in said casing between the countershaft and the fan shaft, gearing between the driving shaft and the countershaft and a suction nozzle communicating with said fan casing. In testimony whereof, I do affix my sig nature inpr'esence of two witnesses.
